帕内特 (Paneth)细胞 (肠内的嗜酸性细胞 )可合成、分泌具有广谱高效抗微生物活性的阳离子抗菌肽 ,α 防御素(α defensin)为其中的一类 ,它是构成机体的天然免疫系统第一道防线的组成成分之一[1] 。小肠黏膜中的α 防御素分子量小、含量微 ,对其提纯和鉴定的难度较大。Selsted
Paneth cells (eosinophils in the intestine) synthesize and secrete cationic antimicrobial peptides with a broad spectrum of highly effective antimicrobial activity. Alpha defensin is one of them, and is a natural One of the components of the first line of defense of the immune system [1]. Small intestinal mucosa α defensin molecular weight, micro content, its purification and identification of the more difficult. Selsted
